TRUCK Application filed October 1 Specification of Letters Patent.

To all u /m nz it 9/10 rower-a Be it known that we Amisr Ax'rown and JL'Lit's Roos, eitizens of the I'nited lates, residing at lassaie, in the eonntt of l"assaie and State of New Jersey have vented eertain new and useful linproxements in Trne s: and we following to he a full. elear. and exaet description of the invention an h a \i'. able others skilled in the art to wh h appertains to make and we the same, %"f,ft""- enee being had to the a -etan anving drawing, and to figures of iei ereih mar thereon, whieh form a part. of this ip rt'liication.

This invention relates to a (ru -h ean he used for transporting lll2lltll;=.l. and is partieularly adapted for use n faeloiies, and is designed so that its top sin-fare or platform ran he raised and lowerwl this type of track heing' parti -nlarl; for use in plants where hearv artieles must he transported and where it is now the haoit of del'iositing a few sheets from a nnn-hiue on a table, then transportiinz'. lrv a few sheets at a time to another where the sheets are to he u ed loeation ease in a great many industries where papeix y 1 sim lar mate ial that sheet metal, eloth. am is heavy in hulk. must he snhieeted at different points to an operation or treatment.

This invention relates to a form rises llat. that is. it does not lh fillt' tilted and is held against any horivontal mmenient, wherehv staehed material is not distnrhed, and if goods on tahles is ar- -tinged in piles they ran he lifted and transported by means of the truek without up setting any of the piles.

The invention is illustrated in companying drawing. in whirlw- Figure l is a side view of the tr n-k with the platform in section and the rear half of the truck cut away to show the ele ating meehanism in side elevation.

The truek eonsists of a frame 1 whit-h is reetai'igular, having the sides 11 and the ends hit The truek is supported on wheels I 13. the rear wheels heing mounted in boxes ll seeured to the frame H) the front wheel heing mount a'l in the swiveled hearings 1.5, the swiveled front wheels permitting the direction of the trnek to he ehanged when nta essar v. The frame it) is provided with reeesses l into whieh tit pins if on the platform it the pins sliding in the res; and preventing horixontal movement the platf rm 1 and extending longiis a main shaft the elevating Fig. 3 shows l tndina ly through the frame l l vvhieh provided on the front end, al thnneh the rear end ean he used if pref rred, ith the handle it) so that the main arllltl l, ean he turned. The main shaft is l prouidrd with worms 21 whieh are in mesh 1 with the wornrgtmrs 2:2 seemed to the transierse shafts 225 whieh are mounted in 1 i l of the frame. The transl are provided with gears 25, l are placed on opposite sides l of the main shaft, that is, the {gear of one ltrannerse shaft is on the right, and the l year on the other transverse shaft is on the l left of the main shaft. eaeh of the gears f heing in mesh with a raek ill. the, rat-k heint: segmental and fa te.'ied."h v in ans of its as. l

These iseparated points at whieh these eams enl gage the platforms. and the rams a ming in lopposite direetions. equalize the strain on ithe platform from the eams and reduce, l the strain on the pins 17.

To minimize the friction we supply the l platform witlr rollers 30 in the hearingsill. i The platform is provided with the marginal flange Whieh rests on the sides and ends l of the frame when the eams are turned to l their lowest position. that is, when the cams i do not support the platform, it rest-s on the 25, We provide a braeket frame by means of the flanr e.

For 3rd pelllng or moving the truck W0 handle 33 connected, by means of the hands stop 36 through which the main shaft 19 passes. A nut 39 is rdaeeal over the portion 40 of the shaft, this portion 1 being serewthreaded, the nut 31 IQShll'lg hetvveen the cheek-pieces 38 so that the nut eannot turn. The screwthreaded portion is so proportioned that the turnin of the main a ft 19 I h causes the nut u.) to travel to one em! of its limit of movement so that when the main shaft is turned in one direetion it stopped by engagement with the stop 36, and when rotated in the other direction, stopped by engaging the hearing 37, the nut then of course co-aeting on the threaded the shaft to stop the To prevent 7 against its stops at either end. we provide Washers 41 which may he of fiher or imila: material and are resilient enough to i revent the binding of the mil; by its h, on the thread.
